EICHLER, OF NEW LISBON, WISCONSIN.,

Letters Patent No.A 85,002, dated December 15, 1868.

' nVIPROvEMENT IN' PORTABLE P'U'JVEPS.

The Scheule referred to in these Letters Patent and making part of the same.

To all whom it mwy concern Be it known that I, F. EICHLER, of ANew Lisbon, in the county of Juneau, and State of Wisconsin, have invented certain new and useful Improvements in Force- Pnmps; and I do hereby declare that the following is :t full, clear, and exact description thereof, reference being had to the accompanying drawings, making part of this specification, and to the letters of reference marked thereon, like letters indicating like parts wl'rereever they occur.

To enable others skilled in the art to construct'and use my invention, I will proceed to describe it.

Iri the drawings- Figure 1 is a vertical cross-section through the centre, and

Figure 2 is a longitudinal vertical section.

My invention relates to a force-pump of peculiar construction, intended for household and farm-use, which can be easily operated by one man, and by. him readilytransported from place to place, as occasion requires.

My pump is constructed follows:

A `represents a strong rectangular box or reservoir, partially covered, intended to contain the water which is to be-forced through and thrown from the pump.

Inside of this box I station a rectangular pump or valve-chest, B, considerably smaller than the box A,

and which is secured by lugs or ears `71. h, bolted on its under side, to the stationary shaft C upon which it rocks or oscillates.

The valve-chest B, I construct of wood or other suitable material, and fasten it securely'together by the metal ii'ame q and bolts c 2'., and it is divided into three cliambe1s,B,B2, and B3, and these are provided ith a series of valves, a, b, c, d, and a port or opening, e, connecting them o'ne with another, and also with the exterior body of waterin the reservoir A.

In the central chamber B`, I place a piston, D, attached to the piston-rod E, which extends up through the stuing-box f, and is attached to an eye or lug, j, on the end of the hand-lever F, which level' is pivotcd at k to the stationary post G, attached to the covered portion of the box A, as shown in'ig. 1.

The water enters the chest through the valves a and b alternately, and flows through into the'chamber B3, from' which it is forced up through Apipe H, attached at the upper end The chamber B3 is connected to chamber B2 by the two valves c and d, one below and one above the piston, and chamber B2 is connected to the chamber B by the port e.

Mypump being thus constructed, operates as follows:

The reservoir. being filled, the lever is forced down, which will drawthe piston up, when the valves b and c`will close, and the' water above the piston in the chamber Bz will, as the chambers Bx and B3 are filled, be forced through valve d into chamber B3, and thence out through the pipe H, and water will at the same Y time rush in through valves a, and fill the void in the chamber B2 below the piston, as shown vby the red' water alreadythere, and forcing it in turn through pipe H, the water in Bl at the same time flowing over lthrough e and lling the chamber above the piston,

and being replaced by water flowing in through b from the reservoir A.

It will thus be seen that a continuous stream will be thrown from the pump without the use of the airchamber, as usual, although it may be attached to prevent any jar when working the pump rapidly.

The object of pivoting the valve-chest is to allow of a lateral movement equal to that of the piston-rod, the upper end of which moves in an arc of a circle. When, for any purpose, it is desired to detach the valve-chest, it may be done by simply withdrawingr shaft G and detaching the piston-rod from-eye j, when the chest may he lifted 4,from its place. 1 i

It is-obvious that any suitable nozzle or pipe may be attached to pipe H, and that the under side of the chest may be so arranged as to permit the attachment of a pipe and thus draw water ti'om a distance.

Thus I construct a pump, which, for farmers and residents of small villages, where there are no engines, will he a great protection against fire, and for washing windows, irrigation, &c., will'accomplish more, and that p better thancan be done by hand, which can be built at a small expense, and may be easily worked by one man, ywho can transport it from place to place, at-will.

Having thus described my invention, What I claim, is- 1 A portable force-pump, consisting of a reservoir or
